Abstract:

The impact of the pre-treatment of cellulose material in  NaOH solution and of microwave radiation on the mechanism of crosslinking β-cyclodextrin with cellulose was investigated in this paper. Citric acid and Na-hypophosphite as catalysts were applied for better crosslinking. Inclusion compounds with tea tree essential oil and cyclodextrines grafted onto  cotton fabric were made in order to verify that  cavities were available for inclusion compounds. The permanence of β-CD on the cellulose fabrics treated was tested by ISO 6330:2012. The properties and structure of the materials treated were characterised by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The breaking force and mechanical damage of the materials were determined according to EN ISO 13934-1:1999. The results indicated better bonding between cellulose and β-cyclodextrin where microwave treatment was applied, the phenomenon of which is of great importance for  long lasting wash durability. In order to quantify the odour releasing behaviour of β-CD treated cellulose fabrics, olfactometric determination of the intensity of odour was undertaken.
